Gastrointestinal Exam Questions Questions
Question 1 of 5
Claire, a 33 y.o. is on your floor with a possible bowel obstruction. Which intervention is a priority for her?
Correct Answer: B
Rationale: The correct answer is B: Measure abdominal girth. In a possible bowel obstruction, measuring abdominal girth is crucial to monitor for signs of bowel distension, which can indicate worsening obstruction. This intervention helps in assessing the progression of the condition and can guide further management decisions. Obtaining daily weights (A) may be important for fluid balance but is not as immediate in this situation. Keeping strict intake and output (C) and encouraging fluid intake (D) are important but not the priority when addressing a possible bowel obstruction.
Question 2 of 5
A person who is 'tongue-tied' can often be treated by surgically cutting the
Correct Answer: C
Rationale: The correct answer is C: frenulum. The frenulum is a band of tissue that restricts the movement of the tongue, causing a person to be 'tongue-tied'. By surgically cutting the frenulum, this restriction is alleviated, allowing for improved tongue mobility and speech. Incorrect choices: A: The uvula is a small, fleshy lobe at the back of the tongue, not related to being 'tongue-tied'. B: The buccinator muscle is involved in chewing and facial expressions, not related to tongue-tie. D: The labium refers to the lips, which are not associated with being 'tongue-tied'.
Question 3 of 5
The esophagus pierces through an opening in the diaphragm called the
Correct Answer: B
Rationale: The correct answer is B: hiatus. The esophagus pierces through an opening in the diaphragm called the esophageal hiatus. The hiatus allows the esophagus to pass from the thoracic cavity into the abdominal cavity. The other choices are incorrect because: A: Fauces is the opening at the back of the mouth leading to the pharynx. C: Glottis is the part of the larynx consisting of the vocal cords and the opening between them. D: Inguinal canal is a passage in the abdominal wall near the groin.
Question 4 of 5
In the regulation of stomach secretions, distension of the stomach activates local reflexes and a parasympathetic reflex. This is called the ______ phase.
Correct Answer: B
Rationale: The correct answer is B: gastric phase. This phase is activated by the distension of the stomach, triggering local reflexes and parasympathetic reflexes to stimulate gastric secretions. The cephalic phase (A) is triggered by the sight, smell, or thought of food. The intestinal phase (C) inhibits gastric secretions and motility. The enterogastric phase (D) inhibits gastric motility and secretion when chyme enters the duodenum. Thus, the gastric phase is specifically related to the distension of the stomach, making it the correct answer.
Question 5 of 5
The liver is a major storehouse for all of the following except one. Which one of the following substance or substances are not stored in the liver:
Correct Answer: B
Rationale: The correct answer is B: calcium. The liver stores copper, iron, vitamins A, B12, D, E, and K, and glycogen. Calcium is primarily stored in bones and teeth, not in the liver. The liver's main functions are to regulate blood sugar levels, detoxify the body, produce bile, and store essential nutrients and energy sources. Calcium is mainly stored in the bones and teeth for structural support and plays a crucial role in muscle function, nerve transmission, and blood clotting. Therefore, the liver does not serve as a major storehouse for calcium.
